lll/'IND SVI-SCREEN.

Application filed November ll, 1914.

To all erf/0m it may concern Be it known that CHARLES Boonen, a citizen of the United States, residing at Fall River, in the county of Bristol, State of lilassachusetts7 have invented certain new and useful improvements in 1Window- Screens; and I do hereby declare the following to be ay full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a window screen. y

llt is well known that tiies collect upon the inside oit a screen and attempt to escape from the room. @it course if the screen were not there it isreasonable to sup' pose that the iies would leave lthe room and taking this into account, l have provided a screen by means of which the flies will be allowed to escape from the room, but will be prevented from entering the same.

An object oia the invention resides in the provision of escape openings in the frame of the screen and thus the screen itseli' is not weakened as there will be no openings therein.

lWith these and other objects in view, such as will appear as the description progresses, my invention comprises the combination and arrangement of parts as set forth in and falling within the scope of the appended claim.

Referring to the drawing: Figure l is a perspective view of the screen. Fig. 2 is a plan view looking down on the upper edge of the screen. Fig. 3 is a sectional view. Fig. i is a fragmental view showing a modiication oi my device.

Referring to the drawing wherein like parts are indicated by like characters throughout the several views: The frame l, which is shown in the drawings is of rectan- `guiar formation, but which may be of any desirable formation to tit the contour of a window consists of side bars l which have grooves 2 therein for the accommodation of the usual beading on the window frame, so that the said sash frame may be raised or lowered. This frame consists of, in addition to the side bars l', upper and lower bars 3 and 4, respectively. The trame is braced at the lower ends by corner brackets 5. rlhe Patented dan. 18, i916.

Serial No. 871,567.

side bars l and the lower bar 4f are preferably rectangular in cross section7 while the upper bar 3 is of Lshape in cross section, thus producing a chamber 6. W'hen the screen is in place in a window, the lower edge of the upperl sash forms a closure for the upper side of the said chamber while the outside thereof is opened, as at 7. The lower portion` 8 of this top bar 8 has a plurality of spaced elongated openings 9. EX- tending over this frame is a piece of screening 10 which is secured to the side bars l and on the upper and lower bars 3 and i by strips 1l, the upper strip forming the fourth side of the openings 9. ldhen the tlies collect upon the inside of the screening l0 the natural tendency for them is to crawl upwardly and in doing' so they pass out of the openings 9 and thus are allowed to escape from the room.

In the modiication oi my device shown in Fig. 4; there is provided a metallic frame 1",

the upper bar 2 of which has a horizontally extending portion 3 in which are located a plurality of openings el and has also an upwardly extending channel piece 5 in which is secured a wooden strip G for bracing the device. In using this device the upper sash forms the upper wall of the chamber with which the openings t communicate in a manner similar to that shown in Fig. l.

It will thus be seen that l have provided a window screen which will allow flies to escape from the room and yet one which will prevent flies from entering the same.

1ili/'hile l have illustrated and described a particular embodiment of my invention, have merely done so for the sake of convenience and I do not wish to be limited to that particular embodiment as it is obvious that numerous changes may be made in the details of construction thereof without in any way departing from the spirit of the invention or exceeding the scope of the appended claim.

TWhat I claim is A window screen comprising a frame consisting of side bars and upper and lower cross bars, the said upper cross bar being l..- shaped in cross section and having a plurality of elongated openings in the horizontal portion thereof, the said upper bar having a and a pluality of stiips securingrthe said f chamber therein, the ends of which are piece of screening to the said frame. 10

formed by the upper ends of the side bars, In testimony whereof, affix. my signa.- and beingconstructed in Such manner that ture, in the presence of two Witnesses. Jcheflowei' portion of the upper sash on the CHARLES ROCHGN. Window will close the nppeia side of said Vitnesses: i chamber, a piece of screening extending over ALEXIS FORAND, Jr., -i the frame and over one side of said openings ARTHUR J. B. CARTER.
